The effect of women’s participation in the labour market on the postponement of first childbirth: a comparison of Italy and Hungary

This paper analyses the effect of increasing female participation in the labour market on the transition to first childbirth. Regional perspectives are considered to help us understand how postponement behaviour is changing over time and at different paces in each region. The analysis is based on the first wave of the Generations and Gender Survey of Italy and Hungary. We use a multilevel event history random intercept model to examine the effect of individuals’ positions in the labour market on the transition to motherhood, controlling for differences in macrolevel factors related to regional backgrounds in the two countries. The regional data for Italy came from the Italian National Statistical Institute, and for Hungary from our imputation developed from the time series available at the national and the regional levels (Hungarian Central Statistical Office, KSH). The postponement of first childbirth is strongly linked to the increasing involvement of women in paid work, but with opposite effects in the two countries. Even if we control for changes in women’s levels of education over time and for shifts in women’s aspirations and levels of attainment in the labour market, we find that being employed remains a risk factor for the postponement of the first birth among Italian women, and a strong protective factor among Hungarian women. At the contextual level, the variables that take into account the regional socio-economic changes provides evidence of important effects on individual behaviour among Italian women, and of only minor effects among Hungarian women. All of the regional breakdowns in both Italy and Hungary show that the postponement of motherhood goes hand-in-hand with the acceptance of deep cultural and socio-economic changes.     

A two-phase optimization method for a multiobjective vehicle relocation problem in electric carsharing systems

A spanning subgraph F of a graph G is called an even factor of G if each vertex of F has even degree at least 2 in F. It was conjectured that if a graph G has an even factor, then it has an even factor F with \(|E(F)|\ge {4\over 7}(|E(G)| + 1)+ {2\over 7}|V_2(G)|\), where \(V_2(G)\) is the set of vertices of degree 2 in G. We note that the conjecture is false if G is a triangle. In this paper, we confirm the conjecture for all graphs on at least 4 vertices, and moreover, we prove that if \(|E(H)|\le {4\over 7}(|E(G)| + 1)+ {2\over 7}|V_2(G)|\) for every even factor H of G, then every maximum even factor of G is a 2-factor consisting of even circuits.     

Service and Life Quality: The Case of Palermo

The research aims at analysing the ``quality' of some services offered to the citizens by the Commune of Palermo. The data available were gathered thanks to a sampling survey carried out in October 1997. The sample is made up of 1008 residents in the city of Palermo and is proportionally stratified according to the quarter of residence. Information was gathered by means of a telephone questionnaire. The answering rate was rather high and a great interest in the subjects dealt was taken.The research wants to individuate the degree of efficiency of the Commune of Palermo, also at administrative level, with some questions concerning the municipal council, taking the expectations of the citizens of the city into account through an analytic survey of the indicators measuring the judgement of the citizen towards the main services. This result will be the starting point of an exhaustive analysis aiming at the individuation of the ``quality of life' in Palermo, which is tightly connected with the services offered.
